There have been widespread gestures of support for Sydney Swans player Adam Goodes this weekend across Australia's sporting arena.

Players and fans from all codes showed they were standing by Goodes after he took indefinite leave over continued booing from opposition supporters.

#IStandWithAdam gained traction on social media, with fans tweeting photos of themselves at games and watching at home, some wearing badges emblazoned with Goodes' face.

The weekend started with Richmond players sporting the Indigenous Round guernseys in their game against Hawthorn on Friday night.

Saturday's game between the Demons and Collingwood saw Melbourne players sporting red, yellow and black arm bands to represent the Aboriginal flag and both teams nodding to Goodes in celebrating goals.

Collingwood's Travis Varcoe also wore an armband with the Aboriginal flag and number 37 (Goodes' guernsey).

The Swans entered the ground through a massive "RESPECT" banner to a roaring crowd.

The usually red home crowd was dotted with Aboriginal flags and fans decked out with the number 37, some waving banners reading "Love Goodes; racism bad", "No room for racism" and "In Goodes we trust".

Team-mate Lewis Jetta dedicated the first goal of the game to Goodes with a war dance, a nod to a similar celebration performed by Goodes in May.

At the seven-minute mark in the third quarter, the crowd stood to applaud Goodes for a full minute.

The Western Bulldogs, like Richmond, wore their Indigenous Round guernseys in Sunday's game against Essendon, while captain Bob Murphy wore number 37 instead of his usual number two for the coin toss before the match.

Also on Sunday Fremantle's Micheal Walters and Danyle Pearce reacted to goals during the Dockers' match against the Giants with pointed celebrations.

In the NRL, Indigenous players Jonathan Thurston and Greg Inglis said they would show their respect to Goodes by celebrating with a war cry if they scored tries in the weekend matches.

A replica of Goodes' number 37 guernsey is also on display at the V8 Supercars event in Queensland.
